TRACE HOLDER AND DETACHER.

SPECIFICATION forming part of Letters Patent No. 276,919, dated May 1, 1883. Application filed August 21, 1882. (No model.)

To all whom it may concern Be it known that I, WILLIAM STANDING, in the county of St. Louis and State of Missouri, have invented a new and Improved Trace Holder and Detacher, of which the following is a full, clear, and exact The object of my invention is to provide a new and improved device for fastening and detaching a trace to and from a single tree at any desired part of the trace.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal side elevation of my improved trace-holder. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal elevation of a modification of the same.

Two arms, A, are hinged to the end of the single-tree B, at the top and bottom, and in the outer ends of the said arms A a roller, (3, is journaled. A clamp-plate, D, which can be straight, but is preferably made curved or with a convex outer surface, is provided with two studs, E, projecting from the inner surface into two barrels, F, attached to the sides of a thimble, B, secured on the end of the singletree B. A screw, Gr, provided with a fixed nut or head, H, at its outer end,projects from the outer end of the thimble B, and against the nut of the said screw the middle of the clamp-plate I) rests. By means of the head or nut H the screw G can be adjusted to prothe thimble B, and thereby the clamp-plate D can be adjusted a greater or less distance from the roller 0, according to the thickness of the trace to be held. The arms A are bulged outward between the roller 0 and the clampplate D-that is, at the part at which the trace vice can be used to hold traces which have a greater width than that of roller 0 and clampplate I). The trace which is held between the clamp-plate D and the roller 0 is drawn in the direction of the arrow at, and is clamped tightly between the roller 0 and the said clamp-plate D, and will thus be held to the end of the single-tree. By pulling the outer ends of the swinging arms A in the inverse direction of the arrow at the trace will bereleased, and can be drawn out from between the roller 0 and the clamp-plate D. Thus, if the horses become unmanageable, and they are to be detached, it is only necessary to pull the roller (3 in the inverse direction of the an row a/ by means of a chain or cord attached to the same and leading to the drivers seat.

an eye, 0, is attached, through which the screw L passes loosely, the nut M being between the clamp-plate N and thesaid eye 0. By turning the nut M the clamp-plate N can be adjusted a greater or less distance from the roller K, according to the thickness of the trace. If the trace is to be released, the clampplate N must be withdrawn or swung back. As the frame of the plate N is mounted on the swinging screw L, the said plate N can swing between the shanks K. The trace can be held at any point of its length by my improved trace-holder, as noperforations or apertures are required in the trace, such as are necessary for trace-holders of the usual construction.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a trace holder and detacher, the combination, with the single-treeB, of the bars A, pivoted to the end of the same, and connected at their outer ends by a roller, 0, and of the adjustable clamp-plate D, substantially as herein shown and described, and for the purpose set forth.
